The Bible is, in my humble and uneducated opinion; the living, breathing word of God. It is still animated by the holy spirit, just as it was when written. It was not written once as a book of instruction, it reveals. It was written to meet all God’s children, where ever and whenever they may seek his word, regardless of their experience or sophistication or culture or condition. When I read one passage, it speaks to me from where I am. If the same passage is read again in different circumstances, a different meaning may be spoken. Two believers will probably hear two meanings, both equally valid. One may be the result of more sophisticated knowledge, the other is not therefore wrong. It is God speaking to us from where we are.
Sometimes I need to listen better.
